Make ppce300c3 tune hard-float by default

2014-04-01T22:38:54+00:00

The tuning file for PowerPC e300c3 is soft-float. In OE-classic it was hard-
float and it should be as the c3 has an fpu. I have modified the tuning file
to include both a hard-float version (using the existing ppce300c3 name) and
an optional soft-float version (called ppce300c3-nf).

The following patch also passes a "--with-cpu=e300c3" argument to GLIBC.
For this to have any effect the sqrt/sqrtf implementations added by the
"glibc.fix_sqrt2.patch" are required and also an additional "Implies" file
(added to the mentioned patch as a separate patch for eglibc_2.19).

Tested with eglibc 2.19 on PowerPC MPC5125.

feature-arm-thumb: Fix missing t2 suffix for armv7a MACHINEs

2014-01-28T00:48:26+00:00

* unfortunatelly that note about armv7 matching also armv7a is no
  longer valid since armv7 include in armv7 was replaced with
  armv6+neon in this commit:

  commit 75b8adbc042e0f65fb1286bc550d02becd3b6aea
  Author: Khem Raj 
  Date:   Tue Mar 27 18:37:45 2012 -0700

    tune/armv7: Delete

  since then thumb and arm feeds had the same architecture
* be aware that this will rename lots of feeds

qemux86_64: Use the core2-64 tune

2014-01-28T00:48:23+00:00

As x86_64 has been "demoted" to an ABI definition rather than a concrete
tune file, replace it with core2-64 for the qemux86-64 machine.

tune: Remove tune-x86_64.inc

2014-01-28T00:48:22+00:00

The tune-x86_64.inc file is conceptually flawed. x86_64 is more akin to
the x86 and x86-32 ABIs defined in arch-x86.inc than it is a concrete
tune file, such as i586 or core2 - to the extent that everything but the
default tune is defined in the arch-x86.inc file. This becomes very
apparant when attempting to include tune-x86_64.inc in the x86 tune
hierarchy.

Remove the tune-x86_64.inc tune file in favor of it being an ABI
definition in arch-x86.inc and relying on the linear hierarchy of
concrete cpu-types in tune-i586, tune-core2, and tune-corei7.

core2_64 should suffice in lieu of x86_64 for all but a couple esoteric
corner cases involving older pre-core2 CPUs. In these cases, if they
exist at all, the BSP can replace the include tune-x86_64.inc with
arch-x86.inc and set the default tune to x86_64.

tune-corei7: Add support for cpu-type corei7

2014-01-28T00:48:22+00:00

corei7 offers a significant advancement since the previous core2
cpu-type described in the tune-core2 file.

From the GCC(1):
Intel Core i7 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3,
               SSSE3, SSE4.1 and SSE4.2 instruction set support.

This offers optimizations for Nehalem and Silvermont (e.g. Bay Trail)
CPUs (and beyond).
